LayerGetPersistentVisibility Method
The persistent visbility setting is used for layers whose visibilty can be changed by a "parent" object. A common case is when a layer is a child layer (ParentId is not nil). In this case, when a parent layer is turned off, then child layers are also turned off. The persistent visibility setting determines what happens when the parent is turned on again.
